In some cases, however, 10c side of the machine, to which a grain-delivery if it is desired, the rain-trough and screw chute or bagging device of any desired concan be retained, and the grain-trough can be arranged to deliver the grain into .the horizontal section a of the conveyer, adjacent to one end of the same, instead of delivering to the ordinary conveyer now in use.

The upper horizontal section a of the elevator is provided with two delivery-spouts a a", one adjacent to each side of the machine, as shown in Fig. 2. When it is desired to deliver grain on one side of the machine, a suitable delivery-chute is connected to one of the spouts a on the side on which it is desired to deliver the grain, and the other spout is provided with a suitable closing device, in this instance a cap a, which is secured to the spout a in any desired way. In Fig. 1 I have shown a bagging device connected to one of the delivery-spouts a and arranged to deliver grain on one side of the machine. WVhen it is desired to deliver grain on the other side of the machine, the bagger or grain-chute will be placed in engagement with the other spout a; and the cap a will be placed over the spout which is not in use.

In Figs. 4 to 10, inclusive, I have shown a slightly-modified form of my improved elevator which is adapted to be attached to the separators of different sizes. In this case the casin g is made of tubing, preferably of sheet iron or steel, and each section is provided with an extensible or telescoping joint, so that it may be extended to accommodate separators of dilferent sizes. The sections are connected at the corners by suitable elbows, hereinafter described. In these figures, C represents the elevator, comprising the lower horizontal section a, the upper horizontal section a, and the lateral vertical section 0 0 Each section is composed of two pieces of tubing of the desired diameter, which may be of any desired cross-section, tubing of circular cross-section being shown. (See Fig. 8.) One of the parts of each section is provided with an expanded portion 0 of any desired length, into which the other part telescopes, as shown in the drawings, (see particularly Fig. 0,) thus forming an extensible or telescoping joint. The tubes are provided at each side of each joint with two or more lugs 0 which are connected by bolts 0 having threaded ends, which are preferably provided with nuts on both sides of each lug, so that the tubes can be held rigidly in any position to which they may be adjusted.

D (see Fig. 5) represents one of the elbows or corner-sections for connecting the straight portions of the elevator. These elbows are secured to the ends of the sections, and each elbow is provided with a sprocket-wheel d, over which the endless chain E, provided with flights e, runs, and I prefer to provide each elbow with ears (1, which are bolted to a perforated lug (Z secured to the body of the separator for supporting the elevator at its corners. The sections of the elevator, preferably the vertical sections, are rigidly secured to the separator-body by means of staple-shaped bolts F, (see Fi 4,) which surround the sections and are secured to the body of the separator, and I prefer this form of attachment also for the elevator shown in Figs. 1, 2, and 3, as indicated at G, Fig. 1.

The bottom section 0 of the elevator is made in the form of a trough open at the top, as shown in cross-section, Fig. 10, to receive the grain from the separator. The upper section 0 is provided at each side of the machine with a delivery-spout c, to which a suitable grain -chute or bagger can be attached, and a cap 0 is employed to close the spout which is not in use and is preferably secured thereto by a bayonet-joint, as shown in Fig. 9. Motion will be imparted to the sprocket-chain by providing one of the shafts of the sprocket-wheels d with a driving-pulley, which is driven from a shaft of the separator in the same manner as the form of elevator shown in Fig. 1.

It will be seen that my improved elevator when attached to a threshing-machine can be rigidly secured thereto, so as not to be jarred loose in transportation. The whole apparatus projects but a few inches from the body of the machine, is very light and compact, and will deliver grain at either side of the machine at will. The grain-chute or bagger can be attached to either one of the grain-spouts in any desired manneras, for instance, by a bayonet joint, as shown for the cap in Fig. 9. a

It will be obvious that when the casing is adjusted to fit a particular threshing-machine the conveyer chain will be lengthened or shortened by adding or taking out links, so as to adapt it to the casing as adjusted.

I do not limit myself to the exact details of construction herein shown and described, as the same may be varied without departing from the principle of my invention.

What I claim, and desire to secure by Letters Patent, is

1. A grain-elevator for a threshingmachine, comprising among its members, a cas ing extending en tirely around the body of the machine, transversely thereof, having its lower horizontal section open along its upper edge to receive grain from the cleaning devices of the machine, and its upper horizontal section provided on its lower side with a discharge-orifice adjacent to each side of the machine, an endless conveyer within said casing, and a detachable closing device for one of said discharge-openings, whereby grain can be delivered at either side of the machine without reversing the travel of said conveyer, substantially as described.
